I'm running it on a RAID 0 arrangement at home - Compaq SMART-2SL controller and a pair of 4.3GB UW drives. Cant remember what the stripe size is off the top of my heead. I did a recreate of my /usr/ports tree last night ( my ports ports.old, then tar -> untar and delete the old one) but I havent subjectively noticed any speedup as yet. I am going to have a play around tonight though and make somemeasurement. Will do the same recerate trick with /usr/src and ssee what the times are to do a du and an rm on each version of it afterwards (can anybody recommend a less crude method to measure the access speed ?) -pcf.
